' all in a single piece which may be plain or decorated, as desired.

Another object of the invention is to provide means for quickly moldingconcretecurbing in the form of a rectangular curb made in a single pieceor'casting of any required size forprotecting graves or for otherpurposes.

These ,and other objects may be attained by the means of theconstruction illustrated in the accompanying drawings, in which F igure'1 is a top plan view of a mold made in accordance with my invention,said view showing a curbing in the mold; Fig. 2 is a top plan view ofthe mold with the curb removed and the inner member or core of the moldcollapsed or adjusted inwardly to permit its removal from the mold boxor frame; Fig. 3 is a longitudinal section taken on the line 3 3 of Fig.1 looking in the direction indicated by the arrow; Fig. 4 is alongitudinal sectional view taken on the line 4-4 of Fig. 1 looking inthe direction indicated by the arrow; Fig. 5 is a longitudinal sectionalview taken on the line of Fig. 2, looking in the direction indicated bythe arrow; and Fig. 6 is a transverse vertical sectional view takenon'the line 66 of Fig. 1 looking in the direction indicated by thearrow.

Referring to the drawings, the numeral 1 designates a mold box or framewhich may be of any required size depending upon the character of thecurb to be molded, said frame being contracted at its upper side andflaring at its lower side as shown in the drawing.

The collapsible core for molding the curbs comprises four members 2, 3,4 and said members having angularly bent ends which are beveled as at 6,said beveled ends adapt ed to be adjustable,-to expand and contractpermitting adjustment.

the core. The members 2 and 3 are each provided with a lug 7. A pivotlatch 8 is connected to a curved lever 9 near the pivot point 10 of thelever said lever being pivoted at 10 upon a lug 11- secured to thememhere 4 and 5 at opposite ends of the core upon the inside-thereof.Connected to the curved levers 9'are suitable links or bars- 12, saidbars being pivoted at their meeting ends upon a bolt 13 which extendsthrough a lever 14 provided with a circular head, the fulcrum of thelever being eccentric to the head. The lever 14 is pivoted at 15 upon apin or rivet which passes through an elongated slot24 in the side 4 ofthe core. A link 16 is provided with a strap passing around theeccentrically mounted circular end of the lever 14, said link beingprovided with a shank 17 provided with notches 18 near the end thereof.The shank 17 is adjustable to regulate the initial positions of thesides 2 and 3, 4- and 5, respectively. The members 2 and. 3 are mountedto slide longitudinally one upon the other by means of the slot 20 andpins 21 while the ends of the members are also permitted to slide uponthe pins 22 extending through slots 23 as shown more clearly in Fig. 6.The members 4 and 5 are mounted to slide longi tudinally one upon theother by means of the slot 2A and pins 15 and 25. The links may beprovided with perforations a for The operation of my invention may bebriefly described as follows :VVith the mold in the condition shown inFig. 2 the concrete material comprising crushed rock, sand, gravel,white sand or granitoid mixed with cementand water is poured in through,the space 7) between the mold box 1, and the collapsible core. It willbe understood that any desired thickness of curb may be made with thisapparatus and that any size of curbing may be molded depending upon thesize of the mold box 1 and the relative di mensions of the collapsiblecore. After the concrete has been placed in the space I), the lever 14isoperated to expand the core and to press the material against theinner wall of the box 1. After the material has be come set, the core iscollapsed by moving the lever 14 in the opposite direction after whichthe collapsible core may be removed. The mold box 1 may be then liftedfrom the curb and the latter permitted to dry.
